"After eight years of war and attempted occupation of Iraq, all Washington has for its efforts is several trillion dollars of additional debt and no Iraqi oil. After ten years of trillion dollar struggle against the Taliban in Afghanistan, Washington has nothing to show for it except possibly some part of the drug trade that can be used to fund covert CIA operations.
America’s wars are very expensive. Bush and Obama have doubled the national debt, and the American people have no benefits from it. No riches, no bread and circuses flow to Americans from Washington’s wars. So what is it all about?
The answer is that Washington’s empire extracts resources from the American people for the benefit of the few powerful interest groups that rule America. The military-security complex, Wall Street, agri-business and the Israel Lobby use the government to extract resources from Americans to serve their profits and power. The US Constitution has been extracted in the interests of the Security State, and Americans’ incomes have been redirected to the pockets of the 1 percent. That is how the American Empire functions."
